Sometimes when rule conditions are met, you may want them to trigger a fault and be alerted immediately. Other times, you may want to only generate a fault when a condition has been met for a period of time. Rule-level aggregates provide the ability to go back through time - series after a rule has been evaluated. For instance, this rule must have been in a faulted state for more than 3 hours before a fault is generated.
From the Mega Navigation, select Rules.
To the right of a Rule, select the ellipsis icon.
Select Manage.
Locate Additional Rule Processing.
Select the drop-down menu, and select from the following:
Aggregate Type | Condition before a Fault will be generated |
|---|---|
Occurrence Count | The rule must have been in a faulted state for a consecutive set number of times. |
Change Count | The rule must have transitioned from a faulted state to an okay state and vice versa a set number of times over the duration specified. |
Percent Active | The rule must have been in a faulted state for a set percentage of time over the duration specified. |
Total Duration | The rule must have been in a faulted state for a set number of hours over the duration specified. |
